  • Publication number: 20220378131
    Abstract: A hairpiece with identical front and back appearances includes a first hair layer, a support layer, and a second hair layer, where the support layer is located between the first hair layer and the second hair layer; and the first hair layer and the second hair layer are fixedly connected to the support layer. In the hairpiece, since the front and back sides of the hairpiece have the same appearance, the user can wear the hairpiece directly, without bothering to distinguish the front and back sides. This avoids the risk of reversing the front and back sides of the hairpiece, and improves the aesthetics and delicacy of the hairpiece.
